Improvement in fulling fabrics



UNITED STATES PATENT QFFIOE.

FRANKLIN D. NAG'LE, OF READING, PENNSYLVANIA.

IMPROVEMENT IN FULLING FABRICS.

Specification forming part of Letters Patent N0. 157,630, dated December 8, 1874; application file December 4, 1874.

To all whom it may concern:

Be it known that I, FRANKLIN D. NAGLE, of Reading, in the county of Berks and in the State of Pennsylvania, have invented certain new and useful Improvements in Fulling Fabrics and do hereby declare that the following is a full clear, and exact description thereof.

My invention relates to the manufacture of felt fabrics; and it consists in a falling compound, to be used in connection therewith, composed of sugar of lead, vinegar, and rye flour, with or without aqua ammonia, formal:- ing the felt compact, as will be hereinafter more fully set forth.

In the manufacture of felt the loosewool is carded and hardened, and afterward placed in the machine used for starting the felting process.

Heretofore, soap has been used to make the felt more compact, which is very objectionable, as it seriously interferes with the stiffening of the goods, and hence the soap must be extracted, when the felting is finished, at considerable loss of time, labor, and expense.

Instead of soap I use a solution or compound composed of the following ingredients, in about the following proportions, viz:

Sugar of lead, two pounds vinegar, six quarts rye flour, one pound, to which may be added, aqua ammonia, one-half pint.

This solution or compound is used to moisten the body-as it comes from the carding-machine, after which the body is put in the fulling mill and hammered, in the usual manner.

By the use of this compound the material is made very close, and cheaper and shorter material may be used.

For instance, the ordinary Waste from wool may be worked in at the rate of two or three pounds to one pound of wool. The presence of this solution or compound in the material does not interfere with the stiffening of the goods, though I prefer to wash out the solution in an alum-bath before stiffening.

I do not confine myself to the-precise proportions ofthe ingredients, as they mayperhaps be varied according to the quality of material used, and quality of felt to be manufactured.

Having thus fully described my invention, what I-claim as new, and desire to secure by Letters Patent, is-

The within-described compound, consisting of sugar of lead, vinegar, and rye flour, to be used in the manufacture of felt, with or without the admixture of aqua ammonia, for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 4th day of December, 1874.

FRANKLIN D. NAGLE.
